Description

A kind of shower nozzle

Technical field

The utility model belongs to spraying or hydrojet field, is specifically related to a kind of shower nozzle.

Background technology

Shower nozzle is usually used in fields such as spraying or water spray, as in the artificial snowing technology, using the snowfall shower nozzle, but existing snowfall shower nozzle is because its structural design, only spray water under high pressure during shower nozzle work from spout, water droplet is not through collision fully, its atomizing effect is not satisfactory, and then has influence on the degree true to nature of artificial snowing; If shower nozzle only is used for water spray, existing shower nozzle atomizing effect is bad, also has influence on the uniformity that shower nozzle sprays, and needs to do further to improve.

Summary of the invention

The purpose of this utility model is to provide a kind of atomizing effect better shower nozzle.

The utility model is achieved through the following technical solutions:

A kind of shower nozzle, the front end of this shower nozzle is a spout, is provided with the feed pathway that communicates with spout in shower nozzle, also is provided with the inlet channel that communicates with spout in this shower nozzle.

Be provided with feed pathway and inlet channel in the shower nozzle described in the utility model, in shower nozzle, feed highly pressurised liquid and gases at high pressure respectively, make highly pressurised liquid and gases at high pressure take place at the shower nozzle place to clash into and drop is pulverized, and through the spout ejection, its atomizing effect obviously improve.

Leading section at this shower nozzle is provided with the adjusting pouring weight, and in when work, shower nozzle is owing to be subjected to the impact of highly pressurised liquid and gases at high pressure, can produce to swing, and the swing that can alleviate the shower nozzle front end behind the adjusting pouring weight is set.

This shower nozzle comprises overcoat and inner core, and in-core is equipped with through hole in overcoat reaches, and inner core cover is located in the through hole of overcoat; One of them be described feed pathway for space in the space of being enclosed between overcoat and the inner core, inner core through hole, the space in the space of being enclosed between overcoat and the inner core, the inner core through hole wherein two be described inlet channel.Be that shower nozzle is made up of overcoat and inner core, during fabrication, overcoat and inner core separate machined assemble again, and this structure is easily manufactured.

The main body of described overcoat is rounded, is equipped with dismountable plane on described overcoat and inner core.Available spanner is on the dismountable plane of dismountable plane to overcoat and inner core, so that shower nozzle is dismantled or installed.

Be distributed in the whole excircle of described inner core by formed described feed pathway in space between described overcoat and the inner core or inlet channel, the described feed pathway or the inlet channel that are distributed in the whole excircle of described inner core communicate with described spout by at least two diffusing chutes.Be that the formed passage in space between overcoat and the inner core evenly distributes in circumferential direction, the liquid or the gas of flowing through are scatter as much as possible, the effect when improving the shower nozzle atomizing.

Described diffusing chute is circumferentially uniform along the axle center of shower nozzle, and described diffusing chute is with respect to the inclined of shower nozzle.This structure makes the liquid or the gas of the diffusing chute of flowing through fully scatter, collide.

Further, also be provided with annular groove at the front end of described diffusing chute, circumferentially described feed pathway of laying or inlet channel are successively through communicating with described spout behind loose chute, the annular groove; By being threaded, and can regulate gap between described annular groove and the described spout between described overcoat and the inner core by this screw thread.The liquid that enters by the adjustable gaps joint of adjusting the annular groove place or the size of gas are to regulate the degree of atomizing.

The specific embodiment

Extremely shown in Figure 7 as Fig. 1, a kind of snowfall shower nozzle, the front end of this shower nozzle is a spout 5, is provided with the feed pathway 3 that communicates with spout 5 in shower nozzle, also is provided with the inlet channel 4 that communicates with spout 5 in this shower nozzle simultaneously.

Particularly, this shower nozzle comprises overcoat 1 and inner core 2, is equipped with through hole in overcoat 1 and inner core 2, and inner core 2 is sheathed in the through hole of overcoat 1, and its neck matches with overcoat 1 by sealing ring 12; Space in inner core 2 through holes is feed pathway 3, the space of being enclosed between overcoat 1 and the inner core 2 is an inlet channel 4, between overcoat 1 and the inner core 2 by being threaded, overcoat 1 is coaxial with inner core 2, and make inlet channel 4 be distributed in the whole excircle of inner core, leading section at this shower nozzle is regulated pouring weight 8 by being threaded, and the main body of overcoat 1 is rounded, is equipped with dismountable plane 9 (being the cutting plane) on overcoat 1 and inner core 2; Front end at inner core 2 circumferentially is evenly equipped with a plurality of diffusing chutes 6, and the chute 6 that looses is with respect to the inclined of shower nozzle, also is provided with annular groove 7 at the front end of the chute 6 that looses, and inlet channel 4 communicates with spout 5 by the chute 6 that looses, annular groove 7 successively.

During use, in inlet channel 4, import high pressure gas by air inlet pipe 10, in feed pathway 3, import water under high pressure by feed tube 11, the diffusing chute 6 of high pressure gas through tilting is ejected into annular groove 7, high pressure gas, water under high pressure compile, collide and water droplet is distributed at spout 5 places and nebulize, atomizing effect is good, and the water droplet of atomizing forms snowflake under low temperature environment, and the effect of artificial snowing is true to nature; In the course of the work, regulate pouring weight 8, the front end of shower nozzle is played stabilization, reduce its swing because the front end of shower nozzle is provided with; Many uniform diffusing chutes 6 are the high pressure gas spout 5 that leads uniformly, and annular groove 7 by regulating inner core 2 front ends and the gap between the overcoat 1 can be adjusted the size of high pressure draught and change fogging degree; With the dismountable plane 9 of instrumental purposes such as spanner on overcoat 1 and inner core 2, can dismantle or install overcoat 1 and inner core 2 easily.
